Personal Computer system:
A computer system is a combination of various input and output devices such as, motherboard, hard drive, rams, CPU, and so on which enables the system to perform various operations needed.
- The basic objective of computer system is to enable their users to perform multiple tasks at the same time, which can be done by using motherboard. In the computer system, the user can decide what function to perform on the system for the specific period. Basically, the computer system is also known as general-purpose programmable system.
- A computer system installs and stores the
operating system in order to make a system work. - Example: A user is working on PC to perform some specific task and at the same time he wants to open some other files or documents, so the motherboard of a computer system assists the user to perform the other task at the same time.
Embedded system: This system also performs the same operations as computer systems does, but the main difference is that it performs only one or some set of operations for the specific period of time. In other words, the embedded system is dedicated to single purpose or a small set of purposes.
- Examples: An ATM machine, air condition, refrigerator, home appliances and many electronic devices.
The similarities between these above mentioned devices are they all perform some specific operation by using embedded system.
An embedded system uses chip to install the operating system within the system in order to make a system works.

- Please solve and show all steps. True or false? Consider congestion control in TCP. When the timer expires at the sender, the value of ssthresh is set to one-half of the last congestion window.arrow_forwardPlease solve and show all work. What are the purposes of the SNMP GetRequest and SetRequest messages?arrow_forwardPlease solve and show all steps. Three types of switching fabrics are discussed in our course. List and briefly describe each type. Which, if any, can send multiple packets across the fabric in parallel?arrow_forward
- Please solve and show steps. List the four broad classes of services that a transport protocol can provide. For each of the service classes, indicate if either UDP or TCP (or both) provides such a service.arrow_forwardPlease solve and show all work. What is the advantage of web caches, and how does it work?arrow_forwardPlease solve and show steps. Consider a DASH system for which there are N video versions (at N different rates and qualities) and N audio versions (at N different rates and qualities). Suppose we want to allow the player to choose at any time any of the N video versions and any of the N audio versions. If we create files so that the audio is mixed in with its matched-rate video and the server sends only one media stream at a given time, how many files will the server need to store (each with a different URL)? If the server instead sends the audio and video streams separately and has the client synchronize the streams, how many files will the server need to store?arrow_forward
- Please solve and show all work. Recall that TCP can be enhanced with SSL to provide process-to-process security services, including encryption. Does SSL operate at the transport layer or the application layer?arrow_forwardPlease solve and show all work. Compute the checksum of the words 1011 1001, 1001 1110, and 0111 1011. Show all work.arrow_forwardPlease solve and show all work. Suppose you can access the caches in the local DNS servers of your department. Can you propose a way to roughly determine the Web servers (outside your department) that are most popular among the users in your department? Explainarrow_forward
- Please solve and show all work. Thank you. Suppose Host A sends two TCP segments back to back to Host B over a TCP connection. The first segment has sequence number 120; the second has sequence number 170. How much data is in the first segment? Suppose that the first segment is lost but the second segment arrives at B. In the acknowledgment that Host B sends to Host A, what will be the acknowledgment number?arrow_forwardIn Matlab script, how would you compute a Reimann sum to approximate the area under the y=sin(x) from a =0 to b = p1/2 with n=6 subintervals using left-endpoints. Use for loop. Assign the result to Lsum.arrow_forwardplease solve using the first step i did which was c(n,n) = 1/C(5,5) = 1. <n=5> P(n,n) = n!/p(8,8)= 8! <n=8>arrow_forward
